Jsci is great! Thanks.
I am no professional mathematician, just a professional java developper. I found this la ibrary, easy to use, easy to extend. Extending LinearMath to solve linear system made of complex numbers was a snap. Further I based on a it an implementation of steepest descent algorithm for solving nonlinear system that would have take me months to develop without Jsci. I would be happy to share my work to the community, but do not know how to contribute
i like that you are working on abstracting the math, although at the moment i am using python more
